Runners and walkers dressed in light emitting suits and holding light sticks make their way up Arthur's Seat as part of a dress rehearsal of a mass participation public art piece called 'Speed of Light' on August 8, 2012 in Edinburgh, Scotland.

The piece which forms part of the annual Edinburgh Festival is set to illuminate the iconic natural monument as hundreds of people make their way up and around the hill, creating streaks of light as they go, Getty Images reports. Each of the walkers' glowing sticks is also set to provide a musical accompaniment as their movement triggers the sticks to create different sounds.
